.Q -This; invention relates to times for haymaking and l1ke lnachinery suchg toninstance 'as swath turners an'd,.s1de' -fde l1very rakes, of the kind'wherein the tines arecontrolled by rotary mechanism which keeps the gends of the tines always directed towards the ground. I v

In connection With tinesv in the class of machine to whichthis invention relates, We and others have already used tines, the free or point ends of Whichhave been curved forwardly in the direction of their-emotion and also tines having their anchored ends formed into coils.

The primary object of the present 'inven-, I tion is to provide a tine which Will be more eflicient in use inasmuch as it Will take hold of the crop more efiectually. so that the crop Will be moved or conveyed by the tines with .less liability of the tines slipping through the crop and less liability of the crop rising v up the tines.

the direction of motion of the tine through the crop, or they may be disposed at various angles-to the plane of movement of the tine.

Instead of forming the undulations or irregular formations by bending the material of which the tine is made, either a straight, corrugated or irregular tine may be pro= vided with additional pieces -or members secured thereto 'for thepurpose of taking hold of the crop more effectually.

Referring to the drawings Figure 1 is a front viewshowing one form of tine constructed in accordance with our invention. 7

Figure 21s a side view thereof.

In;tl1e construction shown in Figures 1' and 2;,j the upper; end of the tine hicl' is to e anshe ed i i e rr ei as winne coil 1, 'While the shank '2 i of r the tinejis formed With a number of lateral loops 3 with intervening straight portions} 4:, the. 7

In the construction shown in Figures '3 and, 4, the uppen portion of thetine is 7 formed as an open coil 6 from which extends the shank portion 7, the major part 8 of which is'ofjwavy or sinuous form, the

Waves, or: curves being arranged laterally and disposedall in thesameplane. The tine terminates in a straight piointpo'r: is tion'9. 1

Our invention is applicable to double tines having a plurality of shanks such as to U shape and anchored atthe bendso as those in which a length of material is bent to constitutea pair of tines; Further,'our

invention is applicable to tines having either straight orfcurved points or free ends and is applicable to tines anchored in any manner to the carrying part In the construction shown; in Figure 5f the Shank portion of which is Cor: a yp ble for applicationlt a" rotating j rugatech is'shown, thesaid tine being ota' head or reel. The'corrugationsjor irreguthey may be in various planes.

It will be understood that in any tith plane oil tines herein describ'ed the corrugations or j irregularities or the additional pieces or;

members fastened to the'tines.;may either.

be disposed transversely to the direction'of' v inoyeinent of the tine through the crop, or 'i f they may be disposed at any other angle in "relation to the direction of movement. f What We claim then is:.- f j 1; -A tine for the rotary tine carrying; I

chines comprising a head formed as an open members of haymakin'g' and harvesting macoil for receivinga securing-bolt, and'a] shank for engaging in the crop, said shank 1 having, intermediate its ends,-a plurality of projecting portions for the purpose oftaking hold of the crop more effectually."

coil for receiving asecu'ring bolt, and a i bent into curves which form V projections.

A tine for the rotary tine carrying members of haymaking and harvesting chines comprising a head formed as an open shank' for engaging in the crop, saidshank hav1ng,- ln'termedlatle. "ItS ends,- a portion which is bent into loops which form projections for the purpose specified. I g

4. A tine for the rotary tine carrying members of ,haymaking and harvesting mach nes comprising ahead formed as an open coil for receiving a securing bolt, and a shank for engaging in the crop, said-shank having, intermediate its'ends, a portion provide-d With a number of projecting shoulders for the purpose specified.

5. A tine for the rotarytine carrying members of haymaking and harvesting machines comprising a single lengthof Wire havingyoneend :bent to form an open coiled spring and having its remaining part arranged to form a shank for engaging With the crop, the said shank being bent at intervalstoform projectionsto {assist in taking hold of thecrop more e'iiec'tually' i,
